. Specification forming part of Letters Patent No.- q)5,2f25. dated July 12, 1870.

To all whom it may concern: 7

Be it known that I, JONATHAN LEWIS, of Washington, in the District of Columbia, have invented new' and useful Improvements in Cultivators; and I do hereby declare that the following is a full and complete description of the construction and operation of the same, reference being had to the accompanying drawings, and to theletters of reference thereon, making part of this specification, iii-which Figure l isa side View. Fig. 3 is a longitudinal vertical section; and Fig. 4- is afront view.

Like letters refer to like parts in the severalviews.

My invention consists in such an arrangeinent of parts that the machine may be used as a marker or cultivator, at pleasure, and so constructed and arranged as to be completely under the control of the operator, and to be readily changed from a marker to a straddlerow cultivator. A represents the two wheels of the machine. B represents the axles.

0 represents the-crosspicce of the frame,

and D the longitudinal beams.

E represents the tongue, and F the hangers to which the plow-beams areattached.

G G represent the plow-beams, and II the standards to which the shares are attached.

I represents an iron rod to which the forward ends of the bean sG Gare attached. A

horizontal bar, F, (shown in Fig. 4,) unites the hangers F, from which rise small pins a a (a c,

Fig. 2is a top view. r

designed for the lateral adjustment of the beams G. This adjustment is effected by the withdrawal of the rod I and placing the beams in their desired position'and returning the rod again to .its place. When the machine is used simply as a marker, the inner beams, G, are

left oft and the outer ones, G, moved to the space outside of e pins (1.

or attached to each pair I L represents I of plows and hi to the forward part of the frame, as seen L, and attached to the middle portion of the beams GG' by means 01; the coupling-rod L, cross-bar M, and staplem, by means of which the plows can be raised out of the ground or pressed into it, at the will of Y the operator,- from his seat N.

The cultivator-teeth, standards H, and beams G G can be adjusted at pleasure, as before described, to suit different widths of rows; or more than two on a side can be used,

it desirable.

Having thus described my invent-ion, what I claim as new, and desire to secure by Letters Patent, i's

The construction and arrangement ol the plow-standards H H, beams G G, levers L,

coupling-rods L, and cross-bars M with thehangers F F, rod I, and adjustingpins a a,

all as and for the purpose specified.
